Diagnostic Use / Indications

Cortisol (hydrocortisone, Cpd F ) is the most abundant circulating steroid and the major glucocorticoid secreted by the adrenal cortex. Physiologically effective in anti-inflammatory activity and blood pressure maintenance, cortisol is also involved in gluconeogenisis, calcium adsorption and gastric acid secretion. As an indicator of adrenal function, measurement of blood cortisol levels is useful in the differentiation of Addison's and Cushing's disease, hypopituitarism and adrenal hyperplasia and carcinoma.
